Netanyahu and his family were not in their residence in Caesarea when the rockets landed.
The identities of those arrested have not been disclosed – but Amir Ohana, Speaker of the Israeli parliament, suggests that regime-critical Israelis are behind it. So does Vice Prime Minister and Justice Minister, Yariv Levin, who accuses the attackers of trying to "undermine the country from within", as well as opposition politician Benny Gantz.
"If the suspicions are true and activists are behind the firing of rockets at the Prime Minister's residence, it should be said clearly: this is not a protest, it is terrorism", Gantz writes on X.
Even Shin Bet chief Ronen Bar expresses himself in similar terms, saying that the incident is "far from a legitimate protest".
On Saturday evening, several protests were held against Netanyahu's warfare in Gaza, with demands for more to be done to free the hostages held in Gaza since October 7.
About a month ago, a drone attack was directed at the same residence in Caesarea, which the Shia militia Hezbollah, which Israel is fighting, took responsibility for.
